O ne last note, I've had some comments on me mispronouncing height as heighth. My possible responses:

1. sometimes I get nervous in front of the camera and have moments where my brain shuts down.

2. We grew up pronouncing it that way.

3. We all make mistakes.....but is it really a mistake ?

4.. Merriam Webster dictionary to my rescue- Heighth- expressed as a dialectal variant of the word height. Part that rises or extends upwards, the highest part
